Abstract
AIM Precise biomarkers for predicting prognosis could help to identify high-risk Crohn's disease (CD) patients to facilitate better follow-up during the postoperative course. In this study, the primary aim is the identification of the most reliable nutrition marker that predicts surgical relapse in CD patients. METHOD We first evaluated the predictive value of various nutrition markers for postoperative surgical relapse in CD patients and identified the advanced lung cancer inflammation index (ALI) as a promising biomarker. Then, we assessed the clinical significance of preoperative ALI in CD patients using two cohorts. RESULTS Preoperative ALI showed the highest correlation with reoperation rate compared with other nutritional parameters in CD patients receiving surgical resection (sensitivity 53%, specificity 86%, area under the curve 0.71). Lower levels of preoperative ALI were significantly correlated with the presence of perianal disease. A lower level of preoperative ALI was an independent prognostic factor for reoperation rate after an intestinal resection (hazard ratio 3.37, 95% CI 1.38-10.12, P = 0.006), and the prognostic impact of preoperative ALI was successfully validated in an independent cohort using the same cut-off value. CONCLUSION Preoperative ALI might be useful for postoperative management of CD patients.

Abstract
Rhizoctonia solani is a soil-borne fungus causing sheath blight. In consistent with its necrotrophic life style, no rice cultivars fully resistant to R. solani are known, and agrochemical plant defense activators used for rice blast, which upregulate a phytohormonal salicylic acid (SA)-dependent pathway, are ineffective towards this pathogen. As a result of the unavailability of genetics, the infection process of R. solani remains unclear. We used the model monocotyledonous plants Brachypodium distachyon and rice, and evaluated the effects of phytohormone-induced resistance to R. solani by pharmacological, genetic and microscopic approaches to understand fungal pathogenicity. Pretreatment with SA, but not with plant defense activators used in agriculture, can unexpectedly induce sheath blight resistance in plants. SA treatment inhibits the advancement of R. solani to the point in the infection process in which fungal biomass shows remarkable expansion and specific infection machinery is developed. The involvement of SA in R. solani resistance is demonstrated by SA-deficient NahG transgenic rice and the sheath blight-resistant B. distachyon accessions, Bd3-1 and Gaz-4, which activate SA-dependent signaling on inoculation. Our findings suggest a hemi-biotrophic nature of R. solani, which can be targeted by SA-dependent plant immunity. Furthermore, B. distachyon provides a genetic resource that can confer disease resistance against R. solani to plants.

Abstract
The vicinal diketones (VDK), such as diacetyl and 2,3-pentandione, impart an unpleasant butter-like flavour to beer. Typically, these are required to be reduced below the flavour thresholds during the maturation (lagering) stages of the brewing process. To shorten beer maturation time, we constructed a self-cloning, bottom-fermenting yeast with low VDK production by integrating ILV5, a gene encoding a protein that metabolizes α-acetolactate and α-aceto-α-hydroxybutyrate (precursors of VDK). A DNA fragment containing Saccharomyces cerevisiae-type ILV5 was inserted upstream of S. cerevisiae-type ILV2 in bottom-fermenting yeast to construct self-cloning strains with an increased copy number of ILV5. Via transformation, ILV2 was replaced with the sulfometuron methyl (SM) resistance gene SMR1B, which differs by a single nucleotide, to create SM-resistant transformants. The wort fermentation test, using the SC-ILV5-homo inserted transformant, confirmed a consecutive reduction in VDK and a shortening period during which VDK was reduced to within the threshold. The concentrations of ethyl acetate, isoamyl acetate, isoamyl alcohol, 1-propanol, isobutyl alcohol and active isoamyl alcohol (flavour components) were not changed when compared with the parent strain. We successfully constructed self-cloning brewer's yeast in which SC-ILV5 was homo-inserted. Using the transformed yeast, the concentration of VDK in fermenting wort was reduced, whereas the concentrations of flavour components were not affected. This genetically stable, low VDK-producing, self-cloning bottom-fermenting yeast would contribute to the shortening of beer maturation time without affecting important flavour components produced by brewer's yeast.

Abstract
OBJECTIVE To investigate the relation between thrombolysis in myocardial infarction (TIMI) frame count (TFC) and coronary blood flow velocity (CBFV) parameters reflecting the degree of microvascular injury in patients with acute myocardial infarction. RESULTS TFC and CBFV were measured after primary coronary angioplasty in 103 consecutive patients with their first anterior wall acute myocardial infarction. TFC correlated inversely with the averaged peak velocity (r = -0.43, p < 0.0001). However, TFC did not correlate significantly with diastolic deceleration time and with the averaged systolic peak velocity (r = -0.16, p = 0.22, and r = -0.23, p = 0.16, respectively). The patients were divided into two groups according to presence (35 patients) or absence (68 patients) of systolic flow reversal. There was no significant difference in TFC between the two groups (29 (16) v 25 (13), p = 0.20). CONCLUSIONS These findings suggest that the TFC reflects epicardial CBFV. However, it is not accurate enough to assess the degree of microvascular injury after primary coronary angioplasty.

Abstract
Cloninger has proposed a seven-factor psychobiological model of personality and has developed the Temperament and Character Inventory (TCI) to measure four temperament dimensions and three character dimensions. This theory of personality may be of great importance in developing an integrated understanding of psychosocial and biological processes underlying the etiology and course of depression, and a large number of studies are being carried out using the TCI to determine the pathology of depression. The present study investigated the factor validity of the TCI in 156 mildly to moderately depressed patients with major depression. The results indicate that the TCI is an internally consistent and factor-analytically valid instrument in patients. Although there was some evidence that a state of depression strengthened correlation between harm avoidance and cooperativeness, the proposed factor structure of the TCI appeared, in general, robust against the state effect of depression, when the state was mild to moderate. These results suggested that the TCI has considerable promise as an instrument for characterizing the underlying personality structure of mildly to moderately depressed patients with major depression.

Abstract
BACKGROUND We investigated whether melancholic and non-melancholic Japanese depressive patients differed in regard to a personality feature, interpersonal sensitivity, as measured by the Interpersonal Sensitivity Measure (IPSM). METHODS In addition to 154 normal controls, 66 remitted melancholic patients and 55 remitted non-melancholic patients filled out the IPSM and two widely-used comprehensive personality inventories, the Temperament and Character Inventory (TCI) and the Munich Personality Test (MPT). The subdivision of patients was made according to three major symptom-based criteria for melancholia (those of RDC, DSM-III, DSM-IV). RESULTS Multivariate and post-hoc univariate analyses of variance revealed significant differences among the three groups in several personality dimensions after Bonferroni's adjustments of P values. While reported scores of both melancholic and non-melancholic patients deviated from normative scores on several personality dimensions, non-melancholic patients reported significantly higher scores on the total IPSM and the 'fragile inner-self' (a subscore of the IPSM) than did normal controls or melancholic depressives. The principal component analysis isolated two factors related to depressive disorders: one factor corresponding to the five IPSM scores; and the other corresponding to harm avoidance, neuroticism and frustration tolerance. The scores on the former factor differentiated non-melancholic depressives from melancholic depressives and normal controls. The scores on the latter factor differentiated both melancholic and non-melancholic depressives from normal controls. LIMITATIONS Prospective studies in which depressive subjects are subdivided into melancholic and non-melancholic subjects will be required to see whether the personality deviations here related to depressive disorders strongly reflect the premorbid personality function. CONCLUSIONS These results indicate that the IPSM scales (particularly, the fragile inner-self scale and the total IPSM scale) are relatively independent of all dimensions included in the two comprehensive personality inventories, and have a capability to describe personality differences between non-melancholic depression and melancholia.

Abstract
The usefulness for evaluation of cerebral hemodynamics using time-resolved projection MRA was studied in normal volunteers and patients of cerebrovascular diseases. Six normal volunteers and ten patients with cerebrovascular occlusive diseases including 6 of IC occlusion and 4 of post EC/IC bypass surgery underwent time-resolved projection MRA on a 1.5 T clinical MRI system. Projection angiograms are acquired with 2 D-fast SPGR sequence with a time resolution of approximately one image per second, 40 images being acquired consecutively before and after bolus injection Gd-DTPA. And all images were calculated by complex subtraction from the background mask in a work station. In normal volunteers, the quality of images of time-resolved projection MRA was satisfactory. The arteries from internal carotid artery through M 2 segment of middle cerebral artery and all major venous systems were well portrayed. In 4 cases of IC occlusion who were assessed the collateral flow through the anterior communicating artery and posterior communicating artery, there were delayed to demonstrate the ipsilateral MCA. However, in 2 cases of IC occlusion that were assessed the collateral flow through leptomeningeal anastomosis, ipsilateral MCA and collateral circulation were not demonstrated. In all patients of post EC/IC bypass surgery, the patency of EC/IC bypass could be evaluated as properly with time-resolved projection MRA as 3 D-TOF MRA. Although the temporal and spatial resolutions are insufficient, time-resolved projection MRA was powerful non-invasive method to evaluate the cerebral hemodynamics via the basal communicating arteries in IC occlusion and identify the patency of EC/IC bypass.

Abstract
We examined dietary intakes among 69 people of three ethnic groups (Yao Chinese, Zhung Chinese and Han Chinese) in the autonomous country of Bama in China where many elderly people have a long life span in 1998. Dietary intake was evaluated using carbon and nitrogen isotope ratios of human hair (delta 13C, delta 15N) standardized by standard gas. The distributions of delta 13C in Yao Chinese and Han Chinese were scattered from -21 to -17/1000, which were close to that of C4 plants such as corn and millet. The distribution of delta 13C in Zhung Chinese was located from -25 to -22/1000, which was near that of C3 plants such as rice, wheat and potato. These values showed a much wider range when compared with delta 13C in Chinese living in urban areas. On the other hand, delta 15N in each group was distributed in the area ranged from 8 to 11/1000. The result of delta 13C was consistent with data obtained from a nutritional survey, but that of delta 15N was a little higher than expected. The carbon and nitrogen isotope ratios of human hair among three ethnic groups showed characteristic distributions, although the relation between these isotope ratios and longevity is uncertain.

Abstract
OBJECTIVE To make a direct comparison of patients with obsessive-compulsive disorder (OCD) and major depression (MD) and a normal control group in terms of the Temperament and Character Inventory (TCI) personality dimensions. METHOD Additionally to 43 patients with primary OCD, 43 MD patients and 43 normal subjects who were matched against the OCD patients for sex and age filled out the TCI. RESULTS Compared to the controls, the OCD and MD patients scored significantly higher on harm avoidance and significantly lower on self-directedness and co-operativeness. The OCD patients scored significantly lower on novelty-seeking than the MD patients and the controls. CONCLUSION Whereas OCD and MD share similar personality deviations on harm avoidance, self-directedness and co-operativeness, OCD is distinguishable from MD in terms of low novelty-seeking. Low novelty-seeking may have a profound relationship to the specific aetiology of OCD.

Abstract
We report an adult onset patient with moyamoya disease showing acute progress after contralateral vascular reconstructive surgery. A 47-year-old female developed cerebral infarction in the left corona radiata. A magnetic resonance (MR) angiography and a cerebral angiogram revealed severe stenosis extending from the terminal portion of left internal carotid artery (ICA) to the M1 portion. The right ICA showed slight stenosis. We performed direct bypass surgery (STA-MCA anastomosis) on the affected left side. MR angiography 1 month after surgery revealed the progressive stenosis of the C1 portion of the right ICA. While measurement of cerebral blood flow (CBF) showed a slight impairment of vascular reactivity to acetazolamide loading in the region of the right MCA, we continued without vascular reconstructive surgery for the right side because there was no ischemic attack. The patient had a transient sensory disturbance of the left upper extremity 16 months after surgery. MR angiography and a cerebral angiogram revealed more progressive stenosis extending from the right ICA to the M1 portion. CBF study showed a low CBF at rest and a negative response to acetazolamide loading in the region of the right MCA. Direct bypass surgery was performed on the right hemisphere. Follow-up study revealed an increment of rest CBF and improvement of vascular reactivity. We underlined the necessity for careful postoperation observation of progressive contralateral arterial stenosis using MR angiography and CBF study in adult onset patients with moyamoya disease.

Abstract
In comparison with 99mTc-ECD SPECT, the usefulness for evaluation of cerebral blood flow by the perfusion images using MRI with FAIR sequence was studied in ischemic stroke patients. Among 27 cases, 15 patients showed lacunar infarctions and 12 patients showed cortical infarctions determined by T2 weighted MR images. FAIR images were obtained as single images at the slice position running through the basal ganglia or corona radiata. The inversion times(TI) were varied, ranging from 800 to 1,400 msec. In 15 patients without definite low perfusions in the SPECT study, FAIR images showed sequentially proxymal arterial branches in early phase and distal arterial branches or capillary beds in the cortical tissues in a late phase as the TI was elongated. Nine of the 12 patients with low cerebral perfusions in the SPECT study showed perfusion defects in FAIR imaging. Five of the 12 patients with a small low cerebral perfusion area in the SPECT study showed a delay of the depiction of cortical arteries along with TI elongation. In 3 patients, ischemic lesions demonstrated by the SPECT study was not shown in the MRI study because of motion artifacts. In conclusion, FAIR imagings are considered to be useful in the evaluation of cerebral flow dynamics in the ischemic stroke patients.

Abstract
BACKGROUND Cloninger's theory of personality, including 4 temperament dimensions and 3 character dimensions, is one of the most noteworthy theories in recent years. Several studies have explored temperament dimensions as a predictor of response to antidepressant treatments in major depression, but these have provided inconsistent results. The present study explored temperament as well as character dimensions, as measured by the Temperament and Character Inventory (TCI), as possible predictors of response to maprotiline, the most-widely prescribed antidepressant in Japan. METHODS 86 consecutive patients with major depression underwent a 16-week open trial of maprotiline. They filled out the TCI at baseline, and were followed up at weeks 8 and 16 by using the Hamilton Rating Scale for Depression. RESULTS Hierarchial logistic regression analyses demonstrated that response to maprotiline was significantly predicted by the cooperativeness score at the 8-week outcome assessment, and by the self-directedness score at the 16-week outcome assessment, after controlling the possible effects of clinical variables on the response. There was no evidence that either temperament dimensions or their 2-way interactions significantly predicted the response. LIMITATIONS Large replication studies with other antidepressants are needed for generalizing the results in this study. CONCLUSIONS The results in this study regarding temperament dimensions seem consistent with findings in previous studies, which are, as a whole, inconsistent with each other. It is suggested that character dimensions (particularly cooperativeness and self-directedness), rather than temperament dimensions, may be important predictors of response to antidepressants. Antidepressants may differ in the personality configurations that predict optimal responses.

Abstract
We investigated age-related changes in the visibility of intracranial arteries on magnetic resonance angiography (MRA) and the influence of risk factors for stroke. We studied 230 adult patients without specific neurological deficits. MRA was performed using the three-dimensional time-of-flight technique with a spoiled gradient-recalled acquisition sequence. We classified internal carotid artery (IC) and the horizontal (M1) and distal (beyond M2) middle cerebral segments into 4 grades. Linear regression revealed a significant negative relation between age and the quality of demonstration on MRA. For IC and M1, the score was significantly lower in subjects with risk factors than in those without. The distal MCA was poorly seen in patients without a history of hypertension or lacunar infarcts. A marked correlation was observed between visibility and age patients with no history of hypertension, diabetes mellitus and hyperlipidaemia. We suggest that atherosclerotic change and decline in flow velocity with normal ageing are factors leading to decreased visibility on MRA.

Abstract
The enantioselective recognition mechanism of secondary alcohol by lipases originated from Candida rugosa and Pseudomonas cepacia was elucidated on the basis of the kinetic study of the esterification of alcohol with lauric acid in isooctane. To obtain inherent kinetic parameters, we utilized a surfactant-coated lipase whose conformation is considered to be an "open" form in a homogeneous organic solvent. Based on the experimental results, the enantioselectivity of lipases was found to be derived from the difference in the V(max) values between the two enantiomers. The same result was observed when lipases of different origin and substrates with different molecular structures were applied. © 1999 John Wiley & Sons, Inc.

Abstract
We examined the diagnostic use of isotropic diffusion-weighted (DW) MRI in 140 consecutive patients suspected of or diagnosed as having an ischaemic stroke. Isotropic DW imaging could demonstrate the lesion responsible for the clinical deficit in patients with multiple cerebral infarcts at an early stage, even small lesions without a perifocal oedema or mass effect. Accurate diagnosis by DW images may, however, be difficult about 2 weeks after the onset of stroke.

Abstract
MR angiograms from 200 neurologically normal subjects aged 30 to 79 years were analyzed to assess the influence of aging and hypertension on the degree of the--visualization of the cerebral arteries. The degree of MR visualization of the cerebral arteries, including the IC, M 1, and distal MCA, was evaluated on a 4-degree scale. IC and M 1 differ in appearance. The MR gradings of each cerebral arteries showed a significant (p < 0.001) negative correlation with age. Hypertension, which is a risk factors for arteriosclerosis, significantly reduced MR grade. The degree of visualization of M 1 and the distal MCA decreased significantly with age in the normotensive group. Therefore, the decrease visualization of the cerebral arteries appears to involve not only cerebral arteriosclerosis but other factors associated with aging.

Abstract
BACKGROUND There is controversy surrounding the factor structure of the Parental Bonding Instrument (PBI), a widely used instrument for assessing perceived parental rearing behaviours. Recent studies have proposed five different factor structures, including Parker et al.'s original two-factor model. METHODS Four hundred and eighteen employed Japanese adults filled out the PBI. Maximum likelihood confirmatory factor analyses were performed to compare the five different factor structures in terms of model-fit. RESULTS Parker's original two-factor structure fitted the data poorly. In general, three-factor structures showed better fit. Among the three-factor structures, Murphy's model and Kendler's model were superior (the adjusted goodness-of-fit index > 0.8), with the latter providing the best fit to the data (the goodness-of-fit index > 0.9). When considering invariance of factor structure across gender subgroups and across age subgroups, only Kendler's model was acceptable. CONCLUSIONS Parker's two-factor structure of the PBI may not be appropriate for assessing perceived parental rearing behaviours in a Japanese population. Three-factor structures, in particular Murphy's model and Kendler's model, are preferable. Kendler's model provided the best fit to the data and was relatively invariant across the subgroups in this study. Thus, Kendler's model might prove to be very important for obtaining a factor structure invariant across different cultures.

Abstract
Although magnetic resonance angiography (MRA) is accepted for showing chronic intracranial stenotic or occlusive lesions, the method has not been practically examined in patients with acute cerebral ischaemia. We carried out three-dimensional time-of-flight MRA in six patients with acute ischaemia treated by local thrombolysis, and compared the findings with those of digital subtraction angiography (DSA). In all patients, MRA before thrombolysis clearly demonstrated the occluded arteries, which corresponded precisely to those shown by DSA. In four patients with complete recanalisation of the occluded vessels after thrombolysis, the recanalisation could be demonstrated by postoperative MRA. In one patient with reocclusion of the recanalised artery, repeat MRA also demonstrated the reocclusion, confirmed by DSA. These results suggest that MRA may be helpful for noninvasive investigation before and after thrombolysis.

Abstract
Preoperative identification of precentral gyrus and intraoperative monitoring of motor evoked potentials (MEPs) were performed to preserve postoperative motor function in seven patients with gliomas near the primary motor cortex. Tumors were astrocytomas in 3 patients, glioblastomas in 2 patients, anaplastic astrocytoma and mixed glioma in one patient each. Preoperative identification of the primary motor cortex was performed by three-dimensional (3D) display of magnetic resonance (MR) images and by functional images using MR imaging and single-photon emission tomography. The primary motor cortex identified by 3D display of MR images coincided well with that identified by functional images. 3D display of MR images was also useful for detecting the relationship between the tumor and the primary motor cortex. Intraoperatively, the central sulcus was confirmed by the finding of phase reversal of cortical somatosensory evoked potential, and this corresponded with the preoperative identifications by 3D display and by functional mapping. The primary motor cortex was stimulated electrically, and MEP (corticospinal evoked potential) was continuously monitored during surgery using electrodes inserted in the cervical epidural space. The amplitude of direct waves of MEPs during surgery was maintained above half of that recorded at the beginning of tumor removal, and all patients showed preservation of preoperative motor function. These results suggest that preoperative identification of precentral gyrus and intraoperative MEP monitoring provide useful information for preserving motor function in patients with gliomas near the primary motor cortex.

Abstract
This study was carried out to resolve the discrepancy of data for the proportion of ascorbic acid and dehydroascorbic acid in persimmon leaves at the final stage of the season and to clarify their cellular distributions using histochemical and biochemical techniques. Fresh persimmon leaves were collected and used on July 31, September 5 and October 7, 1996. Ascorbic acid and dehydroascorbic acid in subcellular fractions were determined by the HPLC method that was found to be the most reliable for separation. The percent of dehydroascorbic acid in the total leaves was found to be almost constant (between 32 and 37%) in all preparations tested. In all preparations, more than 90% of the ascorbic acid and dehydroascorbic acid was found in the soluble fraction. The histochemical detection of ascorbic acid and an electron micrograph of persimmon leaf cells showed that the reactive color, after the reduction of silver nitrate under acidic conditions, in the leaves of all three preparations was mainly found on the face side of columned-type palisade parenchyma cells where chloroplasts were not rich and large vacuoles were seen. On the inner side of the palisade parenchyma cells where chloroplasts were the richest, only weak color development was observed. This study demonstrates that the percent of dehydroascorbic acid in persimmon leaves did not exceed 40% at least until October 7. It also shows that in persimmon leaf cells, ascorbic acid is mainly localized in the cytosol of palisade parenchyma tissue cells where large vacuoles are seen.

Abstract
A cholesterol-free diet containing dried powder of Jew's mellow leaves, persimmon leaves or sweet potato leaves respectively at 5% level as dietary fiber was fed to male Sprague-Dawley rats for about one month. The experiment was conducted twice except for sweet potato leaves. In the groups fed the diet mixed with powders of any of the three different dried green leaves, the hepatic cholesterol concentration significantly decreased. Such lowering was not observed in serum cholesterol concentration compared with the control (cellulose) group. A significant increase in fecal weight was observed in all the groups fed the green leaf samples. All the dried green leaves increased fecal excretion of bile acids per gram or per day compared with the control group in both experiments, but only the dried Jew's mellow leaves showed an increased excretion of neutral sterols. These results suggest that lowering of hepatic cholesterol by powdered green leaves is not necessarily due to the same factor, but to the increased fecal excretion of bile acids due to inhibited enterohepatic circulation in animals given these samples.

Abstract
MR imaging of brain function has been successfully performed at 1.5 T clinical MR unit. In the early studies, functional MRI were performed with simple stimulation such as visual and motor. Recently, many investigators have attempted to demonstrate the specific brain localization of higher brain functions such as memory, imagination, language and so on. In this study, we attempted the functional MRI for motor and word imagination with gradient echo sequences on clinical MR unit. In our experiences, motor cortex was activated on motor imagination task and Broca area was activated on word imagination task, respectively. We demonstrated the higher brain functions were able to be demonstrated on clinical MR unit with gradient echo sequences.

Abstract
A 48-year-old male presented with a very rare case of spinal chondrosarcoma localized in the cervical spinal canal and intervertebral foramen, but without marked destruction of the vertebral column. Spinal chondrosarcoma is characterized by radiological evidence of destruction of the surrounding bone structure and mottled calcification. Magnetic resonance imaging was useful in the diagnosis and determination of the extent of this spinal chondrosarcoma. However, preoperative differential diagnosis of the tumor was not possible based on neuroimaging evidence.

Abstract
This study was undertaken in order to clarify the influence of acute hepatic blood flow occlusion on arterial blood ketone body ratio (AKBR) and systemic hemodynamics. Ten patients for hepatectomy were divided into two groups. Group I was composed of five patients who had clamping of total hepatic blood flow (Pringle's method), and Group II was composed also of five patients who had clamping of the right hepatic artery and portal vein during operation. Ten minutes after clamping blood flow, AKBR decreased significantly in both groups, and a marked reduction in AKBR was observed in group I. During occlusion, cardiac output was reduced significantly, and immediately after declamping, mean arterial blood pressure and systemic vascular resistance index (SVRI) decreased significantly. These changes in hemodynamics in group I were larger than those of the other group. A larger reduction in AKBR was observed during occlusion, and the greater change in SVRI appeared after declamping blood flow. These findings suggest that in the cases with hepatic blood flow occlusion, especially total occlusion, a special attention should be paid to mitochondrial liver dysfunction and hemodynamic changes associated with acute hepatic blood occlusion.

The purpose of this study was to examine the relationship between clinical findings and subgingival relationship between clinical findings and subgingival microbial flora in periodontitis at the first medical examination and after initial preparation. The results obtained were as follows: 1. Clinical findings with the exception of plaque index showed improvement after initial preparation in comparison with the first medical examination. 2. In phase contrast microscopy, both total bacteria and incidence of spirochetes and motile rods decreased after initial preparation in comparison with the first medical examination. 3. Clinical findings with the exception of plaque index were related to the total bacteria and proportional distribution of spirochetes and motile rods in periodontal pockets, observed in phase contrast microscopy. 4. Total bacteria and proportional distribution of black-pigmented Bacteroides in periodontal pockets decreased after initial preparation in comparison with the first medical examination.

Abstract
Left ventricular early filling during hypoxia and reoxygenation was examined in isolated working rat hearts that contracted 300 times/min when perfused with Krebs-Henseleit solution at 37 degrees C. Left ventricular short-axial diameter (LVD = D) was measured with a pair of ultrasonic crystals. The maximum lengthening velocity of LVD [(dD/dt)max] decreased with hypoxia and recovered after reoxygenation (from a control of 20.3 +/- 6.7 to 7.3 +/- 1.7 mm/s after 15 min of hypoxia and to 16.3 +/- 8.1 mm/s after 15 min of reoxygenation; n = 7). However, (dD/dt)max/delta D (where delta D is systolic shortening) showed no significant change with either hypoxia or reoxygenation (from a control of 21.0 +/- 2.9 l/s to 22.2 +/- 2.7 l/s after 15 min of hypoxia and to 22.5 +/- 3.7 l/s after 15 min of reoxygenation; n = 7). Therefore, we concluded that the changes of (dD/dt)max with hypoxia and reoxygenation were caused by the changed systolic shortening and that left ventricular myocardial recoil, expressed by (dD/dt)max/delta D, showed no change with either hypoxia or reoxygenation.

Abstract
In an attempt to determine how the degree of the experimental calculus removal on the metallic plate and its roughness after scaling would be affected by ultrasonics under high or low frequency, quantitative measurement and morphological observation were made. The results obtained were as follows: 1. On the calculus removal, larger effect was obtained by high frequency unit than low frequency. 2. On the roughness of the metallic plate after scaling, larger defect was observed by high frequency unit than low frequency. 3. Scanning electron microscopically, strip like defects were observed under low frequency unit, while exfoliation of the metallic plate in addition to the strip like defects were observed under high frequency.

Colored spatial mapping electrocardiography (ECG) was developed for practical use from Frank lead vectorcardiography using a microcomputer system (CERX-CQ3001). Compared to body surface electrocardiography this new device facilitated easy recording and analysis for display on eight-colored spatial mapping electrocardiography at points equivalent to those on a terrestrial globe at intervals of 20 degrees longitude and 10 degrees latitude. In this study, the extent and direction of the Q waves were easily recognized with the aid of a colored display and mapping electrocardiography. To quantitatively evaluate infarct size, the total Q wave area (sigma Aq) was calculated from the mapping electrocardiograms of 12 patients with anteroseptal myocardial infarction, and compared with thallium defect scores obtained by single photon emission CT (SPECT) and the left ventricular ejection fraction (EF). Defect scores were calculated using short-axis images. Sigma Aq was correlated with defect scores and EF (r = 0.83, 0.45, respectively). This new type of colored spatial mapping electrocardiography proved useful for detecting myocardial infarction and for evaluating infarct size.
